Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, an anti-reflux sputum aspirator comprises a pipeline 1, a joint 3 is sleeved on the pipeline 1, an anti-reflux funnel 2 is fixedly installed in the pipeline 1, a liquid leakage bucket 4 is fixedly installed on the joint 3, a plurality of support rods 5 are fixedly installed on the joint 3, a slide bar 6 is fixedly installed on each support rod 5, a support plate 7 is slidingly installed on each slide bar 6, a plug plate 8 matched with the liquid leakage bucket 4 is fixedly installed on the plurality of support plates 7 together, and a plurality of springs II are fixedly installed between the plug plate 8 and the liquid leakage bucket 4;

The following points are notable:

1. Each supporting plate 7 is provided with a sliding hole matched with the corresponding sliding rod 6, and the upper end of each sliding rod 6 is higher than the lower end of the liquid leakage bucket 4, so that the supporting plates 7 are prevented from falling off the sliding rods 6.

2. The fixed rod 9 is fixedly arranged on the liquid leakage bucket 4, the nut 10 is fixedly arranged on the fixed rod 9, the screw 11 is rotatably arranged on the nut 10 in a threaded manner, the first spring 12 is sleeved on the screw 11, the first spring 12 is positioned between the nut of the screw 11 and the supporting plate 7, and the function of the arrangement is to adjust the elasticity of the first spring 12 so as to change the pressing force between the plug plate 8 and the liquid leakage bucket 4, so that the situation of insufficient elasticity caused by deformation of the first spring 12 after long-term use can be prevented.

3. The supporting plate 7 is provided with a through hole 14, the screw 11 penetrates through the through hole 14, and the screw 11 is in no contact with the through hole 14, so that the screw 11 can conveniently penetrate through the supporting plate 7.

4. The screw cap of the screw 11 is provided with a groove body (13), the end face shape of the groove body (13) is in a cross shape, the depth of the groove body (13) is half of the thickness of the screw cap, and the function of the arrangement is to facilitate manual rotation of the screw 11.

5.
